I am trying to do a lab that needs a inter-area ospf summary address configured I have two loopbacks 137.20.1.17/28 and 137.20.1.33/28. These are then of course on networks 137.20.1.16 and 137.20.1.32. Taking the last octet of the subnets into binary we have:
16= 00010000 32= 00100000 Acording to Doyle and everything else I have read I should be able to summarize by masking the first two bits. I should be able to use: area 11 range 137.20.1.32 255.255.255.192. I am not able to and the router says I have a invalid address/mask. Furthermore the solution to the lab uses "area 11 range 137.20.1.0 255.255.255.0" which creates a summary address to all addresses of 137.20.1.X. What am I missing. This does work and I am able to ping the loopbacks but the math doesn't work for me. I should be able to summarize the 16 and 32 subnets.
